Nets big man Kris Humphries gave Celtics Kevin Garnett a cheap shot in the grill late in the second quarter of tonight’s Nets @ Celtics game. Garnett landed on his butt at the baseline of the TD Garden. Of all people, the Celtics fiesty point guard, Rajon Rondo, to exception to Humphries’ play. So he went at him. Clearly Humphries wasn’t sure how to take it, but regardless the two ended up taking their shoving match right into the stands. That is not something that is going to go over well with David Stern. My guess is that a few people may get suspensions and fines from this incident. Most likely Celtics will be without their starting point guard for at least a few games.
